Brown Deer Waterworks Water Company

The Brown Deer Water Public Utility is a consecutive system to the Milwaukee Water Works. All water distributed by Brown Deer Water Utility is purchased from Milwaukee Water Works. The source water comes from Lake Michigan.

As water travels across land and through waterways, it naturally dissolves various substances. These substances are classified as contaminants. Surface water sources like Lake Michigan can be particularly vulnerable to contamination from both natural processes and human activities.

Potential contaminants in source water include:

• Microbial contaminants (viruses, bacteria, and other microorganisms)
• Inorganic contaminants (salts, metals, and nitrogen compounds)
• Pesticides and herbicides
• Organic chemical contaminants
• Radioactive substances

The EPA establishes regulations that limit contaminant levels in public water systems to ensure safety. All drinking water, including bottled water, may reasonably contain at least small amounts of some contaminants. The presence of contaminants doesn't necessarily indicate a health risk. For more information about contaminants and potential health effects, contact the EPA's Safe Drinking Water Hotline at (800) 426-4791.

The tables in this report show regulated substances detected in Milwaukee's water and Brown Deer's distribution system during 2017. It also includes all contaminants tested under the 2013 Unregulated Contaminant Monitoring Rule: Stage 3 (UCMR-3). All contaminant levels fall within federal and state guidelines.

The tables provide each contaminant's name, maximum regulated level (MCL), public health goals (MCLG), average detected level, common sources, and potential health effects. The presence of a substance doesn't necessarily indicate a health risk - certain amounts of some chemicals are essential for health, while excessive amounts can be harmful.

1. Where does Brown Deer Waterworks water come from?
   Brown Deer Waterworks supplies purchased surface water to Brown Deer, Wisconsin.
2. Does Brown Deer Waterworks test its tap water?

4. Does Brown Deer Waterworks water contain lead?
   Water usually leaves the treatment plant without lead. Lead can enter tap water from older service lines, solder and brass fixtures inside homes, especially when water sits in the pipes. Run the tap before drinking if water has been sitting, and ask the utility about lead testing and service line records.
5. Is Brown Deer Waterworks water hard?
   Hardness depends on the source and changes over time. The annual water quality report lists hardness, or you can test it at home. If it is above about 7 grains per gallon, a water softener sized to your measured hardness will stop scale and spotting.
